These explanatory notes on foiling are directly applicable to Swarovski products, including the abbreviations used.
Foiling
Generically, foiling is the process of mirror under-coating jewellery stones to increase the crystal or stone's brilliance.
Foiled (F)
This indicates that a specific product has
an undercoat of silver mirror that has been coated with Swarovski's newly developed platinum coloured, protective layer.
M-Foiled (M)
This indicates that a specific product has
an undercoat of aluminium mirror which has been applied using a vacuum coating process.
Unfoiled (U)

Though the notes above apply specifically to Swarovski items, the general idea concerning the foiling proces is employed by others and as such, is relevant. Quality of foiling will affect the brilliance of the items. Various manufacturers have differing quality of foiling. Not unexpectedly, Swarovski foiled items generally can boast of higher quality than most.
